 1958   showing the incomplete list as retrieved.  Reduce delay between
 1959   successive mrulist retrieval queries from 30 to 5 msec.  Do not
 1960   give up mrulist retrieval when a single query times out.

 1981 * ntp-keygen private key cipher default now triple-key triple DES CBC.
 1982 * ntp-keygen -M is intended to ignore all other defaults and

 1984   before generating symmetric keys and terminating.
 1985 * Restore IFF, MV, and GQ identity parameter filename convention to
 1986   ntpkey_<scheme>par_<group/host> in ntpd, matching ntp-keygen.
 1987 * Change some error logging to syslog to ignore logconfig mask, such
 1988   as reporting PPSAPI failure in NMEA and WWVB refclocks.
 1989 * ntp-keygen on Windows XP and later systems will now create links
 1990   expected by ntpd.  They are hardlinks on Windows, soft on POSIX.

 2219 * 4.2.7p164 documentation updates re: 'tos orphanwait' expanded scope.

 2227 * [Bug 988] Local clock eats up -g option, so ntpd stops with large
 2228   initial time offset.
 2229 * [Bug 1921] LOCAL, ACTS drivers with "prefer" excluded from initial

 2234   variables.
 2235 * Change "pool DNS" messages from msyslog to debug trace output.
 2236 * Remove unused FLAG_SYSPEER from peer->status.
 2237 * Respect "tos orphanwait" at startup.  Previously there was an
 2238   unconditional 300 s. startup orphanwait, though other values were
 2239   respected for subsequent orphan wait periods after no_sys_peer events.
 2240 * Apply "tos orphanwait" (def. 300 seconds) to LOCAL and ACTS reference
 2241   clock drivers, in addition to orphan parent operation.  LOCAL and ACTS
 2242   are not selectable during the orphanwait delay at startup and after
 2243   each no_sys_peer event.  This prevents a particular form of clock-
 2244   hopping, such as using LOCAL briefly at startup before remote peers
 2245   are selectable.  This fixes the issue reported in [Bug 988].

 2285 * Log failure to fetch time from HOPF_P hardware.
 2286 * Check HOPF_S sscanf() conversion count before converted values.
 2287 (4.2.7p150) 2011/04/13 Released by Harlan Stenn <stenn@ntp.org>
 2288 * Remove never-used, incomplete ports/winnt/ntpd/refclock_trimbledc.[ch]
 2289 * On systems without C99-compliant (v)snprintf(), use C99-snprintf
 2290   replacements (http://www.jhweiss.de/software/snprintf.html)
 2291 * Remove remaining sprintf() calls except refclock_ripencc.c (which is
 2292   kept out of --enable-all-clocks as a result), upstream libs which use
 2293   sprintf() only after careful buffer sizing.
 2294 (4.2.7p149) 2011/04/11 Released by Harlan Stenn <stenn@ntp.org>
 2295 * [Bug 1881] describe the {+,-,s} characters in configure --help output.

 2308 * String buffer safety cleanup, converting to strlcpy() and strlcat().
 2309 * Use utmpname() before pututline() so repeated steps do not
 2310   accidentally record into wtmp where utmp was intended.
 2311 * Use setutent() before each pututline() including first.
 2312 (4.2.7p145) 2011/04/04 Released by Harlan Stenn <stenn@ntp.org>

 2322   timestamps, remove clktest line discipline test program.
 2323 * Remove "signal_no_reset: signal 17 had flags 4000000" logging, as it
 2324   indicates no problem and is interpreted as an error.  Previously some
 2325   bits had been ignored one-by-one, but Linux SA_RESTORER definition is
 2326   unavailable to user headers.
 2327 (4.2.7p142) 2011/03/21 Released by Harlan Stenn <stenn@ntp.org>

 2339 (4.2.7p138) 2011/03/08 Released by Harlan Stenn <stenn@ntp.org>
 2340 * [Bug 1846] MacOSX: debug symbol not found by propdelay or tickadj.
 2341 (4.2.7p137) 2011/03/07 Released by Harlan Stenn <stenn@ntp.org>
 2342 * Use TRACE() instead of DPRINTF() for libntp and utilities, which
 2343   use the "debug" variable regardless of #ifdef DEBUG.
 2344 * Declare debug in libntp instead of each program.  Expose extern
 2345   declaration to utilities, libntp, and DEBUG ntpd.
 2346 * Lock under-construction task, taskmgr objects to satisfy Coverity's
 2347   mostly-correct assumptions about which variables are protected by
 2348   which locks.
 2349 (4.2.7p136) 2011/03/02 Released by Harlan Stenn <stenn@ntp.org>
 2350 * [Bug 1839] 4.2.7p135 still installs libevent ev*.h headers.
 2351 (4.2.7p135) 2011/03/02 Released by Harlan Stenn <stenn@ntp.org>
 2352 * libevent: When building on systems with CLOCK_MONOTONIC available,
 2353   separate the internal timeline (possibly counting since system boot)
 2354   from the gettimeofday() timeline in event_base cached timevals.  Adds
 2355   new event_base_tv_cached() to retrieve cached callback round start
 2356   time on the internal timeline, and changes
 2357   event_based_gettimeofday_cached() to always return times using the
 2358   namesake timeline.  This preserves the benefit of using the never-
 2359   stepped monotonic clock for event timeouts while providing clients
 2360   with times consistently using gettimeofday().
 2361 * Correct event_base_gettimeofday_cached() workaround code in
 2362   sntp to work with corrected libevent.
 2363 * Remove sntp l_fp_output() test now that it uses prettydate().
 2364 * [Bug 1839] 4.2.7p131 installs libevent ev*.h headers.
 2365 * Ensure CONFIG_SHELL is not empty before relying on it for #! scripts.
 2366 (4.2.7p134) 2011/02/24 Released by Harlan Stenn <stenn@ntp.org>
 2367 * [Bug 1837] Build fails on Win7 due to regedit requiring privilege.
 2368 * Provide fallback definitions for GetAdaptersAddresses() for Windows
 2369   build environments lacking iphlpapi.h.
 2370 * Rename file containing 1.xxxx ChangeSet revision from version to
 2371   scm-rev to avoid invoking GNU make implicit rules attempting to
 2372   compile version.c into version.  Problem was with sntp/version.o
 2373   during make distcheck after fix for spurious sntp rebuilds.
 2374 * Add INC_ALIGNED_PTR() macro to align pointers like malloc().
 2375 (4.2.7p133) 2011/02/23 Released by Harlan Stenn <stenn@ntp.org>
 2376 * [Bug 1834] ntpdate 4.2.7p131 aborts with assertion failure.
 2377 * Move sntp last in top-level Makefile.am SUBDIRS so that the libevent
 2378   tearoff (if required) and sntp are compiled after the rest.
 2379 * Use a single set of Automake options for each package in configure.ac
 2380   AM_INIT, remove Makefile.am AUTOMAKE_OPTIONS= lines.
 2381 * Correct spurious sntp rebuilds triggered by a make misperception
 2382   sntp/version was out-of-date relative to phony target FRC.version.
 2383 * Do not cache paths to perl, test, or pkg-config, searching the PATH
 2384   at configure time is worth it to pick up tool updates.
 2385 (4.2.7p132) 2011/02/22 Released by Harlan Stenn <stenn@ntp.org>
 2386 * [Bug 1832] ntpdate doesn't allow timeout > 2s.
 2387 * [Bug 1833] The checking sem_timedwait() fails without -pthread.
 2388 * ElectricFence was suffering bitrot - remove it.  valgrind works well.

 2393 * Provide bug report and URL options to Autoconf.
 2394 * Avoid relying on remake rules for routine build/flock-build for
 2395   libevent as for the top-level and sntp subproject.
 2396 (4.2.7p131) 2011/02/21 Released by Harlan Stenn <stenn@ntp.org>
 2397 * [Bug 1087] -v/--normalverbose conflicts with -v/--version in sntp.
 2398 * [Bug 1088] sntp should (only) report the time difference without -s/-a.
 2399 * older autoconf sometimes dislikes [].
 2400 * Move "can't write KoD file" warning from sntp shutdown to startup.
 2401 * refclock_acts.c cleanup from Dave Mills.
 2402 * Convert sntp to libevent event-driven socket programming.  Instead of
 2403   blocking name resolution and querying one NTP server at a time,
 2404   resolve server names and send NTP queries without blocking.  Add
 2405   sntp command-line options to adjust timing and optionally wait for all
 2406   servers to respond instead of exiting after the first.
 2407 * Import libevent 2.0.10-stable plus local patches as a tearoff, used
 2408   only if the target system lacks an installed libevent 2.0.9 or later.
 2409 * Move blocking worker and resolver to libntp from ntpd.
 2410 * Use threads rather than forked child processes for blocking worker
 2411   when possible.  Override with configure --disable-thread-support.
 2412 * Move init_logging(), change_logfile(), and setup_logfile() from ntpd
 2413   to libntp, use them in sntp.
 2414 * Test --without-sntp in flock-build script's -no-refclocks variety.
 2415 * Avoid invoking config.status twice in a row in build script.
 2416 * Move more m4sh tests needed by libntp to shared .m4 files.
 2417 * Split up ntp_libntp.m4 into smaller, more specific subsets.
 2418 * Enable gcc -Wcast-align, fix many instances of warnings when casting
 2419   a pointer to a more-strictly-aligned underlying type.

 2921 * [Bug 1520] '%u' formats for size_t gives warnings with 64-bit builds.
 2922 * [Bug 1522] Enable range syntax "trustedkey (301 ... 399)".
 2923 * Documentation updates for 4.2.7p22 changes and additions, updating
 2924   ntpdc.html, ntpq.html, accopt.html, confopt.html, manyopt.html,
 2925   miscopt.html, and miscopt.txt.
 2926 * accopt.html: non-ntpport doc changes from Dave Mills.
 2927 * Modify full MRU list preemption when full to match "discard monitor"
 2928   documentation, by removing exception for count == 1.
 2929 (4.2.7p23) 2010/04/04 Released by Harlan Stenn <stenn@ntp.org>
 2930 * [Bug 1516] unpeer by IP address fails, DNS name works.
 2931 * [Bug 1517] ntpq and ntpdc should verify reverse DNS before use.
 2932   ntpq and ntpdc now use the following format for showing purported
 2933   DNS names from IP address "reverse" DNS lookups when the DNS name
 2934   does not exist or does not include the original IP address among
 2935   the results: "192.168.1.2 (fake.dns.local)".
 2936 (4.2.7p22) 2010/04/02 Released by Harlan Stenn <stenn@ntp.org>
 2937 * [Bug 1432] Don't set inheritable flag for linux capabilities.
 2938 * [Bug 1465] Make sure time from TS2100 is not invalid.
 2939 * [Bug 1483] AI_NUMERICSERV undefined in 4.2.7p20.
 2940 * [Bug 1497] fudge is broken by getnetnum() change.
 2941 * [Bug 1503] Auto-enabling of monitor for "restrict ... limited" wrong.
 2942 * [Bug 1504] ntpdate tickles ntpd "discard minimum 1" rate limit if
 2943   "restrict ... limited" is used.
 2944 * ntpdate: stop querying source after KoD packet response, log it.
 2945 * ntpdate: rate limit each server to 2s between packets.
 2946 * From J. N. Perlinger: avoid pointer wraparound warnings in dolfptoa(),
 2947   printf format mismatches with 64-bit size_t.
 2948 * Broadcast client (ephemeral) associations should be demobilized only
 2949   if they are not heard from for 10 consecutive polls, regardless of
 2950   surviving the clock selection.  Fix from David Mills.
 2951 * Add "ntpq -c ifstats" similar to "ntpdc -c ifstats".
 2952 * Add "ntpq -c sysstats" similar to "ntpdc -c sysstats".
 2953 * Add "ntpq -c monstats" to show monlist knobs and stats.
 2954 * Add "ntpq -c mrulist" similar to "ntpdc -c monlist" but not
 2955   limited to 600 rows, and with filtering and sorting options:
 2956   ntpq -c "mrulist mincount=2 laddr=192.168.1.2 sort=-avgint"
 2957   ntpq -c "mrulist sort=addr"
 2958   ntpq -c "mrulist mincount=2 sort=count"
 2959   ntpq -c "mrulist sort=-lstint"
 2960 * Modify internal representation of MRU list to use l_fp fixed-point
 2961   NTP timestamps instead of seconds since startup.  This increases the
 2962   resolution and substantially improves accuracy of sorts involving
 2963   timestamps, at the cost of flushing all MRU entries when the clock is
 2964   stepped, to ensure the timestamps can be compared with the current
 2965   get_systime() results.
 2966 * Add ntp.conf "mru" directive to configure MRU parameters, such as
 2967   "mru mindepth 600 maxage 64 maxdepth 5000 maxmem 1024" or
 2968   "mru initalloc 0 initmem 16 incalloc 99 incmem 4".  Several pairs are
 2969   equivalent with one in units of MRU entries and its twin in units of
 2970   kilobytes of memory, so the last one used in ntp.conf controls:
 2971   maxdepth/maxmem, initalloc/initmem, incalloc/incmem.  With the above
 2972   values, ntpd will preallocate 16kB worth of MRU entries, allocating
 2973   4kB worth each time more are needed, with a hard limit of 1MB of MRU
 2974   entries.  Until there are more than 600 entries none would be reused.
 2975   Then only entries for addresses last seen 64 seconds or longer ago are
 2976   reused.
 2977 * Limit "ntpdc -c monlist" response in ntpd to 600 entries, the previous
 2978   overall limit on the MRU list depth which was driven by the monlist
 2979   implementation limit of one request with a single multipacket
 2980   response.
 2981 * New "pool" directive implementation modeled on manycastclient.
 2982 * Do not abort on non-ASCII characters in ntp.conf, ignore them.
 2983 * ntpq: increase response reassembly limit from 24 to 32 packets, add
 2984   discussion in comment regarding results with even larger MAXFRAGS.
 2985 * ntpq: handle "passwd MYPASSWORD" (without prompting) as with ntpdc.
 2986 * ntpdc: do not examine argument to "passwd" if not supplied.
 2987 * configure: remove check for pointer type used with qsort(), we
 2988   require ANSI C which mandates void *.
 2989 * Reset sys_kodsent to 0 in proto_clr_stats().
 2990 * Add sptoa()/sockporttoa() similar to stoa()/socktoa() adding :port.
 2991 * Use memcpy() instead of memmove() when buffers can not overlap.
 2992 * Remove sockaddr_storage from our sockaddr_u union of sockaddr,
 2993   sockaddr_in, and sockaddr_in6, shaving about 100 bytes from its size
 2994   and substantially decreasing MRU entry memory consumption.
 2995 * Extend ntpq readvar (alias rv) to allow fetching up to three named
 2996   variables in one operation:  ntpq -c "rv 0 version offset frequency".
 2997 * ntpq: use srchost variable to show .POOL. prototype associations'
 2998   hostname instead of address 0.0.0.0.
 2999 * "restrict source ..." configures override restrictions for time
 3000   sources, allows tight default restrictions to be used with the pool
 3001   directive (where server addresses are not known in advance).
 3002 * Ignore "preempt" modifier on manycastclient and pool prototype
 3003   associations.  The resulting associations are preemptible, but the
 3004   prototype must not be.
 3005 * Maintain and use linked list of associations (struct peer) in ntpd,
 3006   avoiding walking 128 hash table entries to iterate over peers.
 3007 * Remove more workarounds unneeded since we require ISO C90 AKA ANSI C:
 3008   - remove fallback implementations for memmove(), memset, strstr().
 3009   - do not test for atexit() or memcpy().
 3010 * Collapse a bunch of code duplication in ntpd/ntp_restrict.c added with
 3011   support for IPv6.
 3012 * Correct some corner case failures in automatically enabling the MRU
 3013   list if any "restrict ... limited" is in effect, and in disabling MRU
 3014   maintenance. (ntp_monitor.c, ntp_restrict.c)
 3015 * Reverse the internal sort order of the address restriction lists, but
 3016   preserve the same behavior.  This allows removal of special-case code
 3017   related to the default restrictions and more straightforward lookups
 3018   of restrictions for a given address (now, stop on first match).
 3019 * Move ntp_restrict.c MRU doubly-linked list maintenance code into
 3020   ntp_lists.h macros, allowing more duplicated source excision.
 3021 * Repair ntpdate.c to no longer test HAVE_TIMER_SETTIME.
 3022 * Do not reference peer_node/unpeer_node after freeing when built with
 3023   --disable-saveconfig and using DNS.

 3686 * Update libisc code using bind-9.6.1-P1.tar.gz, rearrange our copy to
 3687   mirror the upstream layout (lib/isc/...), and merge in NTP-local
 3688   modifications to libisc.  There is a new procedure to ease future
 3689   libisc merges using a separate "upstream" bk repo.  That will enable
 3690   normal bk pull automerge to handle carrying forward any local changes
 3691   and should enable us to take updated libisc snapshots more often.
 3692 * Updated build and flock-build scripts.  flock-build --one is a way

 3694   clone's first build on a machine with autoconf, automake, etc.

 3706 * [Bug 1315] "interface ignore 0.0.0.0" is ignored.
 3707 * add implicit "nic ignore all" rule before any rules from ntp.conf, so
 3708   "nic listen eth0" alone means the same as "-I eth0".
 3709 * add wildcard match class for interface/nic rules.
 3710 * fix mistaken carryover of prefixlen from one rule to the next.
 3711 * Ensure IPv6 localhost address ::1 is included in libisc's Windows IPv6
 3712   address enumeration, allowing ntpq and ntpdc's hardcoding to 127.0.0.1
 3713   on Windows to end.

 4168   I've now spent eleven months of a sabbatical year - 7 days a week, 6-10
 4169   hours most days - working on NTP. I have carefully reviewed every major
 4170   algorithm, examined its original design and evolution from that design.
 4171   I've trimmed off dead code and briar patches and did zillions of tests
 4172   contrived to expose evil vulnerabilities. The development article is in
 4173   rather good shape and should be ready for prime time.
 4174 
 4175   1. The protostats statistics files have been very useful in exposing
 4176   little twitches and turns when something hiccups, like a broken PPS
 4177   signal. Most of what used to be syslog messages are now repackaged as
 4178   protostats messages with optional syslog as well. These can also be sent
 4179   as traps which might be handy to tiggle a beeper or celltext. These, the
 4180   sysstats files and cryptostats files reveal the ambient health of a busy
 4181   server, monitor traffic and error counts and spot crypto attacks.
 4182 
 4183   2. Close inspection of the clock discipline behavior at long poll
 4184   intervals (36 h) showed it not doing as well as it should. I redesigned
 4185   the FLL loop to improve nominal accuracy from  several tens of
 4186   milliseconds to something less than ten milliseconds.
 4187 
 4188   3. Autokey (again). The enhanced error checking was becoming a major
 4189   pain. I found a way to toss out gobs of ugly fat code and replace the
 4190   function with a much simpler and more comprehensive scheme. It resists
 4191   bait-and-switch attacks and quickly detect cases when the protocol is
 4192   not correctly synchronized.
 4193 
 4194   4. The interface code for the kernel PPS signal was not in sync with the
 4195   kernel code itself. Some error checks were duplicated and some
 4196   ineffective. I found none of the PPS-capable drivers, including the atom
 4197   driver, do anything when the prefer peer fails; the kernel PPS signal
 4198   remains in control. The atom driver now disables the kernel PPS when the
 4199   prefer peer comes bum. This is important when the prefer peer is not a
 4200   reference clock but a remote NTP server.
 4201 
 4202   5. The flake restrict bit turned out to be really interesting,
 4203   especially with symmtric modes and of those especially those using
 4204   Autokey. Small changes in the recovery procedures when packets are lost
 4205   now avoid almost all scenarios which previously required protocol resets.
 4206 
 4207   6. I've always been a little uncomfortable when using the clock filter
 4208   with long poll intervals because the samples become less and less
 4209   correlated as the sample age exceeds the Allan intercept. Various
 4210   schemes have been used over the years to cope with this fact. The latest
 4211   one and the one that works the best is to use a modified sort metric
 4212   where the delay is used when the age of the sample is less than the
 4213   intercept and the sum of delay and dispersion above that. The net result
 4214   is that, at small poll intervals the algorithm operates as a minimum
 4215   filter, while at larger poll intervals it morphs to FIFO. Left
 4216   unmodified, a sample could be used when twelve days old. This along with
 4217   the FLL modifications has made a dramatic improvement at large poll
 4218   intervals.
 4219 
 4220 - [Backward Incompatible] The 'state' variable is no longer reported or
 4221   available via ntpq output.  The following system status bit names
 4222   have been changed:
 4223   - sync_alarm -> leap_alarm
 4224   - sync_atomic -> sync_pps
 4225   - sync_lf_clock -> sync_lf_radio
 4226   - sync_hf_clock -> sync_hf_radio
 4227   - sync_uhf_clock -> sync_uhf_radio
 4228   - sync_local_proto -> sync_local
 4229   - sync_udp/time -> sync_other
 4230   Other names have been changed as well.  See the change history for
 4231   libntp/statestr.c for more details.
 4232   Other backward-incompatible changes in ntpq include:
 4233   - assID -> associd
 4234   - rootdispersion -> rootdisp
 4235   - pkt_head -> pkt_neader
 4236   See the change history for other details.
